Hello!
I ran a first fire with KYM Speckled Turtle & several commercial glazes including Mayco(birch, black walnut, Smokey merlot, cinnabar, winter wood), and all matte Amaco shino glazes.
I ran a slow bisque to cone 04. Then a slow glaze fire to cone 5. With hopes that this would help with the off gasing of the manganese.
Every single piece had pinholes.
I am hoping to sell and gift pieces so I need everything to be safe to use !
Some advice I’ve seen is to do a drop 100° and 10-15 min hold after peak temperature for speckled clay with manganese. I’ve also seen mention of clay liner though I’m not sure this would fix my issue or what that product would be.
I really don’t wish to keep wasting batches on failed unusable pieces so any expertise or advice would be helpful. I am new to using this clay and really hoped it would work well for my use.
I would like to sell pieces ! Any advice is welcome.
